From White Dwarf To Neutron Star To Black Hole: Accretion, Gamma-ray Bursts, And Their Aftermath
Abstract
When white dwarfs with massive companions experience accretion-induced-collapse, the newborn neutron star may continue to accrete until its mass becomes larger than the maximum neutron-star mass. The resulting black hole may have special properties that allow it to be identified post-collapse. We present a set of such evolutions, punctuated by gamma-ray bursts, and assess the expected rates. An individual system may exhibit a remarkable range of high-energy states: supersoft source, ultraluminous x-ray source, hard x-ray binary, and gamma-ray bursts.
